Soryu photos and diagrams on the way to winning (maybe)

S, in Comments [at October 24, 2015 at 11:26 AM], advised that Soryu SS-508 due to be launched next week (November 2, 2015) will include the newly developed TCM (Torpedo Counter Measures) MOD (Mobile Decoy) as well as a NAE (Noise Augmentation Emitter). Photos and diagrams appear difficult to find?

S indicated that from recent news "I feel that Japan may win the CEP." To which Pete says yes that is possible, but still long to wait. The winner may be announced next year or later. Alternatively the Australian Government might just eliminate one competitor and the two remaining competitors might then go through a tender process. 

The recent news, which looks favourable for Japan, is from News Corp and the The (Adelaide) Advertiser via The Australian.

The News Corp article http://www.news.com.au/national/japan-is-offering-secret-technology-to-win-submarine-contract/story-fncynjr2-1227571858283 included diagrams and photos from the Japanese Bid Team including 1 to 3:

The (Adelaide) Advertiser via The Australian http://www.theaustralian.com.au/news/future-submarines-first-look-inside-soryu-sub-as-japan-ups-ante-in-contract-bid/story-e6frg6n6-1227579060243 included photos (4 to 7) taken inside Soryu submarine No. SS-507 (Jinryu) which was launched last year and is due to be commissioned in March 2016.

Future Australian Soryus will need to be larger for longer missions - which will require extra diesel fuel, food and water storage capacity. The combat system may be larger and/or need extra electricity to run it. The Japanese designers will use different hull coatings to tropicalise Australian Soryus from rust/corrosion in the warmer seas that missions take place.

Design adjustments from the Japanese Soryu would include longer and wider bunks to accommodate the larger Australian frame. Some alterations for women on board noting Japanese crews are all male affairs. The kitchen will need larger ovens to bake more bread.

Mr Ikematsu, Director, International Cooperation Division, Acquisition, Technology and Logistics Agency (ATLA), Japanese Ministry of Defence (variously known as JMD, JMOD or plain MOD) emphasised the focus on involving Australian industry and opined choosing Japan would be less risky because Japan already builds large conventional submarines.

Final proposals from the three contenders are due by November 30, 2015. By early 2016 the Government may decide on a partner/winner and a build option. Alternatively the Australian Government might just eliminate one competitor and the two remaining competitors might then go through a tender process.
